need to delete yahoo email

I have the address and password, but my computer isn't recognized, nor do I recognize the recovery email, so I cant access my old account. some of my banking information has been sent to that address and I need for either the emails to be deleted, the email account to be deleted, or to regain control of the account. There is a chance that the email has been compromised as well as the account has been inactive for more than 2 years, which means it should have been deleted by now unless someone was logging onto it. Thank you for your time.
